Converting PNG to SVG is fundamentally a tracing operation, not a format change. PNG stores pixels; SVG stores geometric primitives. Going from a pixel grid to scalable vector paths requires interpreting the bitmap and drawing approximating shapes around regions of similar color. The result is genuinely scalable — you can resize freely without pixelation — but it is not a perfect reproduction of the source. Photographic content traces poorly because every pixel-level color variation becomes a shape, producing huge SVGs that defeat the purpose. Logos, icons, line art, and high-contrast graphics trace cleanly because they have a small number of color regions with well-defined boundaries.
This converter uses the imagetracerjs library, a JavaScript port of vector-tracing algorithms similar to potrace. The PNG is decoded into an RGBA bitmap, the bitmap is segmented into color regions using a configurable palette, each region's boundary is traced into a path, paths are simplified using Bezier approximation, and the resulting paths are emitted as SVG path elements. The whole pipeline runs in your browser without any server upload.
Tracing parameters control the trade-off between fidelity and file size. More colors and finer detail produce a larger SVG that more closely matches the source; fewer colors and coarser tracing produce a smaller SVG with a more stylized feel. Defaults are tuned for logos and icons; complex images may benefit from a tracing pass with adjusted settings, or may simply not be good candidates for vectorization.
Vectorizing a PNG is most useful when you need to scale the image beyond its original resolution. Logos in particular often arrive as PNGs at modest size and need to appear crisp on billboards, retina displays, and large-format prints. A vector trace produces an SVG that scales without quality loss; the tradeoff is fidelity to the original pixels.
SVG is also significantly more compact than PNG for graphics with few colors and large flat regions. A PNG icon at 256×256 might be 8 KB; the equivalent SVG with two or three colors is often under 1 KB. For UI icon libraries delivered to a web frontend, vector versions reduce bundle size and improve sharpness on all display densities.
Drop a PNG, choose tracing settings, generate an SVG.
imagetracerjs implements a multi-stage pipeline: color quantization reduces the bitmap to a fixed number of colors using k-means clustering or median cut; edge detection identifies pixel boundaries between regions; contour tracing follows boundaries to produce closed polygons; line-and-curve fitting approximates polygons with Bezier curves to reduce path data.
The algorithm parameters that matter most are number of colors (typical: 4–32), pathomit (paths shorter than this many pixels are discarded as noise), ltres (line tolerance — how far an edge can deviate before being split into a new segment), and qtres (quadratic curve tolerance — how aggressively curves are smoothed). The defaults work well for logos; complex images benefit from per-image tuning.
Output is standard SVG 1.1 with path elements. Each color region becomes one path with a fill attribute. The resulting file opens in any browser, vector editor, or SVG-aware design tool. File size depends primarily on path count and node density; a typical traced logo is 1–10 KB.
